A type confusion bug in TypedArray prior to commit e6ed9c1a4b02dc219de1648f44cd808a56171b81 could have been used by a malicious attacker to execute arbitrary code via untrusted JavaScript. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected. • https://github.com/facebook/hermes/commit/e6ed9c1a4b02dc219de1648f44cd808a56171b81 https://www.facebook.com/security/advisories/cve-2023-25933 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

A null pointer dereference bug in Hermes prior to commit 5cae9f72975cf0e5a62b27fdd8b01f103e198708 could have been used by an attacker to crash an Hermes runtime where the EnableHermesInternal config option was set to true.

There is a vulnerability in the fizz library prior to v2023.01.30.00 where a CHECK failure can be triggered remotely. This behavior requires the client supported cipher advertisement changing between the original ClientHello and the second ClientHello, crashing the process (impact is limited to denial of service). • https://github.com/facebookincubator/fizz/commit/8d3649841597bedfb6986c30431ebad0eb215265 https://www.facebook.com/security/advisories/cve-2023-23759 • CWE-617: Reachable Assertion •
